" Application filed June 24, 1907. Serial No. 380,643.

To alllwhom it may concern:

Be 1t known that I, FRED MiKEAL, a citi zen of the United States ofAmerica, and a `resident of J acksboro, county of Jack, State of Texas,have invented certain new and useful Improvements in @ar-Couplers, ofwhich the following is a specification.

My invention relates to car couplers and more particularly to that typein which a cou ling-pin and link are employed and the stri ing togetherol' the cou )ling heads causes the pin to drop through the link andeffect the coupling without necessitating a trainman being present.

The object of this invention is to provide nn improvement in the meanswhereby the pin can be set preparatory to coupling, and

automatically released by the contacting ot the coupling heads. l

To that end it consists in the construction, arrangement and combinationof parts which are hereinafter more fully described and claimed,

In theaccompanying drawings which forni a lpart of this speciication:*l`igure 1 is a si e elevation of a coupling head, having my inventionapFplied thereto, `the coupling pin being set. `ig. 2 is a sideelevation of the same with the coupling pin released, and Fig. 3 is aplan of the showing of Fig. 2.

Coupling head 1 has projecting inwardly from its face, a [hired mouthedhorizontal coupling-link chamber 2, and extending therethrough from thetop a vertical couplingin chamber 3, immediately' behind Whic lies avertical aperture 4.

Suitably journaled to the bottom 'of the.

coupling head, in brackets 5 and 5, the latter of which may beintegral`with the head if desired, is a crank shaft 6, extending to theside of the car and being /provided on its outer end with an arm andhandle 7, and midway between brackets 5 andV 5a with forwardly extendingarm 8. Ratchet wheel 20 is firmly mounted u on said crank shaft adjacentto the side o the head. Iivoted at the end of arm 8 is the link 9 whichexh aperture 4 (the latter being large enoug to permit free (play), andhas its upper end bent forwar and bifurcated for the reception andpivotingof the upper end of couplin -pin 10. Coiledsprin 11 encirclescrank s midd e portion a proximatel Q straight and abutting against t euppersi( eof the arm 8,

aft 6 and has its ends abutting against the lower face of head 1 in sucha manner as to exert a downward pull on arm 8.

tod 1li is suitably mounted upon the exto?- rior f head 1, in brackets15, and is pressed outwardly b coiled-sprin 17, its outer end )rejectings 'ghtly beyon the face of the ead and its inner end having pivotedthereto one end of link 18, the other end of which is pivoted to plawl19, which latter is in turn pivoted to t e side of head 1 in such aposition as to engage the tooth of the ratchet 20, and thus preventclock-wise rotation of crank shaft 6 when the coupling-pin 10 is raisedinto a )roper setting position "lhus it is evident that the pawl 19constitutes a brake lever for the vertical rod 9. Y i

Any convenient means can be employed whereby the coupling-pin 10 can beraised from the ytop of the car. In the `particular embodiment of myinvention herein shown such means consist of a link 13 pivoted at thebottom to link 9, and at the to to one end of the lever 14, bydepressing the other end of which, it is obvious the coupling-pin willbe raised.

The operation of the device is as follows When it is desired to makencoupling, the trainman, if at the side of the car, turns the .crankcounter clockwise until, by meansof 'link- 9, the lower end ofcouplinpin 10 is raised just above the link c er 2, the arts 6, 7 and 8thus constitute a setting ever for the pin. In this position the awl 19,properly positioned and maintaine by coiled-spring 17, en ages the toothof ratchet wheel 20 and hol s the coupling-pin thus suspended. If thetrainman is on top of the car, he accomplishes the Asame result by meansof l-ever 14 and link 13.` 'Ilhe'carsI to be coupled are then broughttogether, the coupling-link on the other car enters the ilared mouthlink chamber 2, and its coupling hetd` striking the rod 16, pushes it inwardly andthus causes pawl 19 to be withdrawn from the tooth ,efratchetwheel 20, and the couplin`g-pin iifdue to its weight and the tension ofsprin 11 transmitted through arm 8 and link 9, i rops through thecoupling link and effects the coupling.

What I claim and desire to secure by Iletters Patent is:-

1. In a 4car-cou ler, the combination with a couplingin, o a verticallymovable rod adapted to ift the said pin, a crank shaft cooperatingtherewith, a ratchet wheel mount- 2. `In near coupler the cumbimrticnwith a. couph pin, of n. vertically movable rod adaJte to lift the saidPune bmlrclevcr .1w ote intermediate efits ends, midone en restrammietheseid rod, a releasing pin projecting yond the face of the coupler endconnected by a. link to the other end of the brake lever, and a. s ringtending to throw 'the brake lever to heid the vertical rod, sul)uetahtally as described.

3.111 a car coupler the combination with u. suitable head havin# e linkchamber in the forward face thereelaend u vertical bore ex tendingthrough the heed in the rear of said 2 chamber, nl' c coupling pin, crod vertically movable in the seid bore and engaging the scid lpin, c.setting lever pivcted below the wup er in the rear uf the said rod, andpivotcd tc the latter, u. brake lever for the rod )ivated en the head, areleasing pin mounte on the head, and connected by c link tc one end ofthe llmke lever, and@ coiled s ring tending te reject the releasingpiniieyond the ferwam fece of the coupler and acting on the breke lever tehold the vertical red raised.
